Polypropylene (PP) bags used by smallholder farmers in Nigeria do not provide effective protection for stored produce due to insect boring activities. Deltamethrin incorporated polypropylene, ZeroFly® (ZF) and ZeroFly® Hermetic Storage Bags are technologies with potential to improve protection of stored food commodities against insect attack. Therefore, a 12-month study was conducted in Ibadan, Nigeria to determine the suitability and potential of combined postharvest bag technologies involving ZeroFly® (hermetic and non-hermetic) bags for smallholder farmers when exposed to Sitophilus zeamais and Prostephanus truncatus infestation pressure. Cleaned but un-fumigated 50-kg lots of maize were used to fill bags in each of the following 8 treatments — PP and ZF bags alone, diatomaceous earth-treated maize in PP and ZF bags, single and...

Contributions of such weather parameter fluctuations to the changes in entomological data obtained within a community under implementation of a promising vector control intervention should be taken into account. This study reports on inter-annual changes in entomological indices within two rural communities, one of which was under insecticide-treated durable wall lining (DL) installation. Community-wide DL installation was followed by monthly meteorological data and pyrethrum spray mosquito collections for 2Â years in intervention and a similar neighbouring community (control). Human blood meal and sporozoite ELISA tests were conducted on female mosquitoes collected alongside PCR identification of subsamples. Mosquitoes collected at the intervention site were tested in cone susceptibility assays against subsamples of installed DL materials collected on a 6-mont...

However, for timely and effective vector control activities, the distribution of these important vectors in local communities is crucial. We therefore determine the distribution of the members of Anopheles gambiae s.l. in Oyo State, Nigeria Methods: Larval stages of Anopheles mosquitoes were collected from identified mosquito breeding sites in six localities (Oluyole, Eruwa, Oyo, Ojoo, Bodija, and Ogbomoso) in Oyo State and reared to adults. Three to five days old adult emergence were identified morphologically using standard methods. A total of 100 mosquitoes were selected from each of localities for molecular analysis. DNA were extracted and Polymerase Chain Reaction (PCR-ID) followed by restriction endonucleases digestion was used for molecular identification. Results: A total of 58 larval breeding sites were sampled out of which 12 (20.7%) had Anophelines only, 21 (...

Fungal and insect pests of cultivated P. ostreatus were examined. Fungi from infected mother spawn of P. ostreatus were isolated, characterized and identified, while various insect pests on P. ostreatus were also collected and analysed. The plates showing micrographs, morphological and cultural characteristics of fungal isolates obtained were recorded. Fungi species isolated from infected mother spawn of P. ostreatus were identified as Aspergillus flavus, A. niger, Cladosporium sp., Penicillium oxalicum, Fusarium oxysporium and F. verticilliodes. The growth of Cladosporium sp. was slow on Potato Dextrose Agar (PDA) plates compared to Aspergillus sp. and Fusarium sp. which was very fast. Insect belonging to the orders Collembola, Diptera and Araneae were encountered on the cultivated P.ostreatus. T...

Knockdown and mortality effects of an organophosphate Actellic 300 CS and pyrethroid K-Othrine WG 250 insecticides on the field-collectedwere assessed bimonthly from July to November 2014, using World Health Organization (WHO) cones bioassay test. Knockdown and mortality rates were subjected to statistical analysis using χand Studenttests. Result of the bioassay test onshowed that plywood surfaces had the best residual knockdown activity of Actellic 300 CS with knockdown rate above the WHO-recommended threshold limit of ≥95% for 30 days after treatment. This was followed by mud surface with knockdown rates ≥95% threshold limit 15 days (97%) after treatment. The lowest knockdown rates of less than 95% were observed on cement surface throughout the assessment period. However, the knockdown rates of mosquitoes on delt...

One of the most commonly reported tick-borne illnesses in the United States, Lyme disease, is caused by Borrelia burgdorferi sensu stricto (ss), which is transmitted by ticks in the Ixodes ricinus complex (Mead 2015). Ixodes scapularis, the blacklegged tick, is considered the primary vector of B. burgdorferi ss in the northeastern and northcentral United States and I. pacificus, the western blacklegged tick, is the primary vector in western states. In the United States alone, more than 30,000 cases of Lyme disease are reported each year but it is believed that the actual number of cases may reach as high as 300,000 (Mead 2015). In California, members of the B. burgdorferi sensu lato (sl) complex, including B. burgdorferi ss, B. americana, B. bissettiae (formerly B. bissettii), B. californiensis, B. carolinensis, and several uncharacterized genospecies have been detected in I. pacificus and mammals throughout the state (Lane et al. 2013, Foley et al. 2014, Padgett et al. 2014, Swei et al. 2015). Two pathogenic tick-borne Rickettsia species are also known to occur in California: R. rickettsii, the causative agent of Rocky Mountain spotted fever (RMSF), documented in Dermacentor species and R. philipii (formerly Rickettsia sp. 364D), likely transmitted by the

Methods: C ommunity-wide cross-sectional study was conducted in J une 2012 using pretested structured questionnaire and interview schedule to collect information on perception, prevention and treatment of malaria among the residents. Results: M ajority of the respondents attributed malaria to mosquito bites and prevented the disease through multiple means including the use of long-lasting insecticidal nets ( 60 %) , insecticide sprays ( 54 %) and mosquito coils ( 48 %) alternatively. A ll the respondents spraying insecticides shortly before bed time outdoors during night hours. F ifty three percent of the respondents treated the last malaria episode at the hospital/clinic, and the remaining ( 47 %) employed self-medication. O nly 6 . 1 % of those who engaged in self-medication used artemisinin combination therapy drugs. Conclusions: C ombined use of long-lasting insecticidal nets and insecticide sprays call for investigation of behavioural and physiological insecticide resistance in the mosquitoes present in this area. N ight time outdoor staying behaviour mandated by spraying of insecticides and possible switch of the vectors to bite outdoor at early night hour also necessitate incorporation of outdoor mosquito control into the malaria elimination plan for this locality. Likewise, the implication of self-medication despite high literacy levels is that campaigns against such practice may not yield except quality healthcare service is cheaply accessible to all
